Stretching mate device for exercising purposes

ABSTRACT

A stretching mate device includes a shaft having two hand grips rotatably secured on the ends for allowing the hand grips to be rotated relative to each other and relative to the shaft. The hands of two persons may solidly or firmly or stably hold and grasp the hand grips for stretching or exercising purposes. The stretching mate device may also be used to conduct weighing exercises as that of the dumbbells. A spring may be secured to the hand grips for recovering the hand grips after the hand grips are rotated relative to each other against the spring.

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a stretching mate device, andmore particularly to a stretching mate device for exercising purposes.

[0003] 2. Description of the Prior Art

[0004] Typically, when two persons are conducting the stretchingexercises, the two persons may have their fingers bent and engaged andhooked with each other for conducting the stretching exercises. However,the fingers of the two persons may not be forcefully engaged or hookedwith each other, because the bent fingers may not be solidly orforcefully hooked with each other. Accordingly, two or more persons maynot conduct stretching exercises with each other.

[0005] The present invention has arisen to mitigate and/or obviate theafore-described disadvantages of the conventional stretching exercises.

SUMMARY OF THE INVENTION

[0006] The primary objective of the present invention is to provide astretching mate device for exercising purposes.

[0007] The other objective of the present invention is to provide astretching mate device including two hand grips that may be rotatedrelative to each other.

[0008] The further objective of the present invention is to provide astretching mate device including a spring biasing device for recoveringtwo hand grips that are rotated relative to each other.

[0009] In accordance with one aspect of the invention, there is provideda stretching mate device comprising a shaft including two ends, and twohand grips rotatably secured on the ends of the shaft respectively, forallowing the hand grips to be rotated relative to each other andrelative to the shaft. The hands of every two persons may solidly orfirmly or stably hold and grasp the hand grips for stretching orexercising purposes. The stretching mate device may also be used toconduct weighing exercises as that of the dumbbells.

[0010] The hand grips each includes an inner portion having a wavysurface formed therein for engaging with fingers of users, and forallowing the users to comfortably holding or grasping the hand grips.

[0011] A device is further provided for recovering the hand grips, andincludes a spring having two ends secured to the hand grips respectivelyfor applying a spring biasing force against the hand grips and forrecovering the hand grips after the hand grips are rotated relative toeach other against the spring.

[0012] The spring is a coil spring and is engaged on the shaft. A sleeveis preferably further provided and engaged on the spring and the shaftfor shielding the spring and/or the shaft, and for preventing the users'fingers from being hurt by the spring.

[0013] Further objectives and advantages of the present invention willbecome apparent from a careful reading of a detailed descriptionprovided hereinbelow, with appropriate reference to accompanyingdrawings.

[0017]FIGS. 4, 5, 6, 7 are schematic views illustrating the operation ofthe stretching mate device for exercising operations.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0018] Referring to the drawings, and initially to FIGS. 1-3, astretching mate device for exercising purposes in accordance with thepresent invention comprises two hand grips 10, 20 each including a wavyinner surface 11, 21 for receiving or for engaging with the fingers ofthe users, and each including a stepped hole 12, 22 formed therein. Ashaft 30 includes two ends engaged through the stepped holes 12, 22 ofthe hand grips 10. 20, and threaded with the lock nuts 31, for rotatablysecuring the ends of the shaft 30 to the hand grips 10, 20 and forallowing the hand grips 10, 20 to be rotated relative to the shaft 30.The hand grips 10, 20 are preferably rotatably secured to the ends ofthe shaft 30 and may not be moved toward or away from each other.

[0019] A spring 40, such as a coil spring 40, is engaged on the shaft 30and includes two ends 41, 42 secured to the hand grips 10, 20respectively for applying a recovering or spring-biasing force againstthe hand grips 10, 20 and for recovering the hand grips 10, 20 backwardto the original position after the hand grips 10, 20 are rotatedrelative to each other against the spring 40. A sleeve 43 is engaged onthe shaft 30 and the spring 40 for shielding or covering the spring 40and for preventing the users' hands from being hurt by the spring 40.The shaft 30 and/or the hand grips 10, 20 may be made of plasticmaterials, or may be made of metal materials or the other heavymaterials, for allowing the stretching mate device to be used to conductweighing exercises as that of the dumbbells, best shown in FIGS. 4 and5.

[0020] In operation, as shown in FIGS. 6 and 7, the hands of two personsmay hold the hand grips 10, 20 of the stretching mate devicerespectively and may rotate relative to each other by rotating the handgrips 10, 20 relative to each other against the spring 40. The users maysolidly and stably hold and grasp the hand grips 10, 20 and may easilyconduct stretching exercises, for example.

[0021] Accordingly, the stretching mate device in accordance with thepresent invention may be provided for exercising purposes, and includestwo hand grips that may be rotated relative to each other, and includesa spring biasing device for recovering two hand grips that are rotatedrelative to each other.

[0022] Although this invention has been described with a certain degreeof particularity, it is to be understood that the present disclosure hasbeen made by way of example only and that numerous changes in thedetailed construction and the combination and arrangement of parts maybe resorted to without departing from the spirit and scope of theinvention as hereinafter claimed.
